Patent ES-344181-A1 (ES)
Title: Improvements in or relating to Stepping or Synchronous Motors
IPC: H02P8/04
Filed: 1967-08-17
Abstract: A synchronous motor is energized from an oscillator whose frequency automatically increases from an initial value, chosen so that the rotor can "lock on" from rest, to the desired operating frequency. As shown, the motor is a stepping motor having a permanent magnet rotor and four stator windings A energized sequentially from the pair of transistor bistable multivibrators shown at P. These are switched by pulses from a free running astable multivibrator comprising transistors 1, 2 and capacitors 3, 4, at a frequency controlled by the conduction of a transistor 24 which depends upon the state of charge on a capacitor 40. Oscillations start when switch S is opened capacitor 40 is initially discharged and the controlling voltage at the emitter of 24 is substantially the -24 volts on line 12. This voltage linearly approaches zero, and the oscillator frequency thereby increases, as capacitor 40 is charged at constant current through transistor 38. The frequency of the supply to each stator winding A is one quarter of that of the driving pulses from astable multivibrator 1, 2. In an alternative embodiment (Fig. 4, not shown) the motor is a synchronous machine having a single main stator winding and an auxiliary winding in series with a capacitor so that it starts in the required direction. Both windings are energized via a transformer supplied from an RC oscillator as described in Specification 1,119,708, which is a multivibrator whose frequency increases as a capacitor is charged from the supply via a resistor which is tapped so that the final frequency can be selected. A capacitor in series with the motor causes the motor voltage to increase with frequency. The first embodiment is for driving a magnetic tape and the second for the turntable of a record player. Suitable components are listed.
